|“||Fun is overrated! If you're gonna be a champion, I suggest you start acting like one!||„|
|~ Trenton to his son Pride after he catches him playing with Stripes.|
Sir Trenton is the father of Trenton's Pride, a racehorse who was a three-time winner of the Kentucky Open and one of the main antagonists of Racing Stripes.
Sir Trenton is an arrogant, gruff black thoroughbred who sees his son Pride having no purpose other than to to carry on the Trenton legacy. Trenton also sees the Kentucky Open as his property and believes that Stripes might ruin it, and is willing to do whatever it takes to prevent Stripes from racing, even if he has to resort to aggression.
He wants Stripes out of the pictures hoping his goons to kill Stripes and Sandy. He was about to murder Sandy if Stripes wins the Kentucky Open. He calls Tucker a rail old rat and threatens to kill him by calling him a rail and hoping he would kill him for interfering when his friends are escaping the stables because his animal freak show had got in his way for the last time and also, those legs will not carry Tucker far.
When hiring his goons kill the zebra, Trenton never shows sympathy or remorse or compassion and threatens to kill Sandy and Tucker for not getting thanks to him. Tucker and Trenton got into a rivalry and he said that he will never beat a Trenton. Stripes would’ve brutally beaten to death if Sir Trenton wins and killing Sandy.
All in all, Trenton is an arrogant jerk who will stop at nothing to keep his winning streak intact. He will murder anyone who gets in his way.
At the fence between Nolan Walsh's farm and the racetrack, Stripes meets two young horse foals training to race, Trenton's Pride and Ruffshodd, but when they have fun racing with Stripes, Pride's father, Sir Trenton, notices catches and confronts the two foals. When Pride states that they were only having fun, Trenton retorts that "Fun's overrated". and that he has to start acting like champion. Trenton then forbids the two foals from playing with Stripes again.
Years later, Trenton sees adult Pride & Ruffshodd chatting with Stripes, and tells Stripes "Stop bothering my son." Ruffshodd claims that he and Pride were trying get Stripes to stop bothering them, but Trenton won't buy it. He then leaves.
Later at the Kentucky practice, Trenton tells Stripes that he is a zebra, not a racehorse. Trenton then tells Stripes that he will never be a racehorse and leaves. Stripes is discouraged by this revelation. But his friends help him overcome it. When Shetland Pony, Tucker (who had trained Trenton without getting any thanks from him) states that he is in for a huge surprise, Trenton scoffs "You'll NEVER beat a Trenton."
When Trenton hears that Stripes has been signed in to race, he is furious and is willing to stop him. When Pride insists that he can win the race fair and square, Trenton blows him off by ignoring him, stating that he is unwilling to take that risk.
On the night before the race, Sir Trenton and several other thoroughbred (excluding Pride) ambush Stripes and racing jumper Sandy while they make up for an argument they had the previous day. Trenton stated that Stripes will get murdered from tomorrow’s race card. Trenton then kidnaps Sandy and threatening to hurt and kill her if he races while another horse knocks Stripes unconscious. His goons would’ve brutally beat Stripes to death while Tucker, Franny and Goose woke up him by the lake.
At his shed stables at the racetrack, Trenton has forced Sandy into her own stable. Trenton instructs Pride to win the race, at all cost, with Pride stating he'll do his best. While Trenton listens to his Mozart. Goose the Pelican, Franny the Goat and Tucker the pony then arrive at the stables to save Sandy, thinking of a way to distract him. Goose tries to defecate and poop on him, but misses and instead crashes into a wall, causing a bucket to fall on his head and at Sir Trenton's mercy.
Before Trenton can finish Goose off, Buzz and Scuzz distract the racer by luring him into his own stable, and locking him inside of it. Tucker and Franny free Sandy. Sir Trenton roars at Tucker that he called him an old rail rat, and he might’ve known he behind this. He and his friends have gotten in his way for the last time, those legs won’t carry him far and he will threatens to kill Stripes, Sandy, Tucker and Franny for interfering and reputations the racehorse.
As the furious Sir Trenton watches them leave, he violently bangs his hooves on his stable door. Trenton manages to escape and he follows the group to the fence at Nolan's farm. Trenton furiously states to Stripes that "The affections of a filly" do not make him a race horse. Stripes retorts that he does not want to be a race horse, he is a zebra going to the big race. Trenton watches them leave for the racetrack with a cold look on his face. But then said, "You runts don't know what you're in for.", meaning that he's a little bit worried about what will happen.
Sir Trenton is not seen again in the film, and it is unknown how he reacted when Stripes won the race at the film's end. After Stripes won the race, Sir Trenton would’ve redeem himself and is very proud of Pride of winning the race and learns his lesson.
Sir Trenton plans to kill Stripes for winning the race because he will not allow him to run in his competition. He is often rudely calling him a beast as well. He is very rude to Stripes and often he became vicious, murderous, even dangerous.
He often insults Stripes by saying that will never be a racehorse and even, Stripes was nothing of the kind and often he does not like him, stated that Stripes will be taught a lesson, hiring his goons to kill him. But, unfortunately, hoping he will get hurt. He never shows remorses and often shouts at Stripes because the affections of Sandy don’t make him a racehorse, but if Stripes wins the race, he would murder anyone who gets in his way,
Trenton often kidnap her and threatened to murder her in a cold blood if Stripes races. He often lock Sandy in her stables and calls her a little girl.
Trenton was one of Tucker's ungrateful former racehorses-in-training before Nolan and Tucker retired from training.
|“||Hey kid! See what happens when you forget your place? The racetrack is no place for a zebra. (Stripes: What'd you call me?) A zebra, which is what you are. You didn't really think you were a horse did you? (Stripes: But I am a horse. A racehorse!) You're nothing of the kind. You're lunch for a lion, and that's about it. One thing's for sure, kid. You will NEVER be a racehorse.||„|
|~ Sir Trenton revealing to Stripes that he's a zebra and insulting him.|
|“||They can't be serious! This will NOT STAND. I will not allow that beast to run in my competition! (Pride: Please, Father! Don't interfere, I can win it fair and square.) That is not a risk I'm willing to take!||„|
|~ Trenton vowing to stop Stripes from racing.|
|“||Well, this is disappointing.||„|

|~ Sir Trenton threatening to murder Stripes from race card.|
|“||Oh, Don’t fret bout her. As long as if you don’t race tomorrow, I wouldn't dream of harming her. You, on the other hand need to be taught a lesson. SHOW HIM!’ KILL HIM!!'||„|

|~ Trenton yelling at Tucker while after they freeing Sandy while threatening to kill him while Franny and Tucker were rescuing Sandy.|
|“||YOU WON’T GET AWAY WITH THIS! (Sandy: Leave us alone, Trenton.) You and your foolish friends have accomplished nothing! The affections of a filly DO NOT MAKE YOU A RACEHORSE! (Stripes: You know something, Sir Trenton? I don't wanna be a racehorse. I'm a zebra and I'm going to the big race.)||„|
|~ Trenton yells at Stripes because his friends even accomplished but the affections of his Gang never make him a racehorse yet they actually did.|
